indicate the rate of travel in miles in accordance with the amount of current which is passing through it. i

The odometer is operated by the make and break of the current effected bythe wheel 21 and brush 25. The gearing which con,- nects this wheel 21 with the shaft 8 so pro ortioned that the contact piece 24 will me e one complete revolution, and complete the circuit tin'oughthe brush 25 oncein every one-tenth of a mile traveled by the irontwhccl 2 and by this completion eithe circuit the indicator on the odometer is moved forwardone point, each oint onthe dial being marked one-tentn 0 a mile. .-1t will be understood that any other'nnu'king and any ot..erproportion between the speed i of the shaft 8 and the wheel 21 may he med so long as there is a proper COl'l'fl-w'P INlGIIF-G between the marking on the dial and the speed of treveL 1 Tue eating, 6 row be made practically airtight so as to cxc udo water and moisture irom the working part: of the upparattw, and since all of t..e working parts are wit. intnis casing and nothing extends outside of it, except tee driving stult and the circuit wires, very ell'ectunl protection is provided for t.e apparatus and the chance for accidental derangement is reduced to a minimum.

It willof course be understood that any desired number of indicating dials may he placed in the circuits at groper places in the ve..icle for obserxalicn tuB occupant.

Hevin thus described t to invention, what is claime is: l

1. 1110 combination with a rotary shaft, of e dynamo electric machine geared to be operetetl thereby, an odometer, a circuit connecting said odometer-with said dynamo electric machine, moans operated by said machine for melting and brealdng the circuit to operet-e the odometer, a speedometer and a continuous circuit connecting the said spendometer to said dynamo electric mnchinc.

2. The combination with the front axle of a motor vehicle, of a dynamo electric machine carricd thereby, means for operating said dynamo from the front wheel; a npood mneter and an odmncter, circuits comm-ting said speedometer and odometer with said dynamo, and moons operated by said dynn, mo I'm-making nod breaking the odmncicr circuit 3. The cemhinnl ion with a; vehicle monnh ed on wheels, of a. dynamo carried thereby, means for operating said dynamo by the roration of a. when! of the vehicle, a speedometor, a. con: innons circuit connecting said dynemo with said speedometer, an odometer. u
